LAMP-SHADE.

SPECIFICATION forming part of Letters Patent No. 348,232, dated August31, 1886.

(No model.)

T0 0% whom it may concern.-

Be it known that I, IIENRY S. Mynns, acitizen of the United States,residingin New York city, in the county of New York, in the State of NewYork, have invented certain new and useful Improvements in Lamp-Shades,set forth in this specification and the drawings thereof.

The object of my invention is to produce a cheap, convenient,and durableshade forlamps and other lights,which is not liable to get out of order,like the ordinary shades suspended by fragile wires or frames, and bywhich the danger of burning the paper by accident 01 carelessness isavoided.

Figure 1 of the drawings represents the piece or section thatforms theupper part of the shade; Fig. 2,the piece or section that forms thelower part. Fig. 3shows the two pieces or sections united together, andFig. 4 the completed shade in place on a lamp-chimney.

Similar letters indicate corresponding parts.

The smaller piece or section,A,Fig. 1, forms the upper part of the shadeand comes in direct contact with, and its circular edge 0 c restsdirectly against or upon, the chimney of the lamp. That it may endurethe heat to which it is exposed, it made of heat-proof or fireproofmaterial. Gt may be made of metallic or mineralsubstances,properlyformcdto allow for expansion and contraction, or of paper, cloth, leather, andsimilar substances rendered sufficiently fire-proof; but the substan ccfound preferable and best adapted for the purpose, be cause absolutelyfireproof and most convenient for use, is asbestus, made into shcetslikepaper, from which the required piece is readily cut. The width of thepiece may be varied as desired, but a width of about an inch and a halfis generally sufficient to protect the attached paper against beinginjured by the heat. To stiffen the asbestus and also to prevent itsfuzzing or particles from tearing off, it is given one or more thincoats of silicate of soda or fire-proof paint. A number of perforationsof different shapes, or simple round holes, as shown in the drawings,are made through the piece, which are designed to check or diminish theheat as it is conducted downward through the asbestus, and which alsoserve to ornament and render the shade more cheerful to the vision.

The larger piece or section, B, Fig. 2, forms the body and lower portionof the shade, and is cut from and consists of ordinary paper, which maybe of any kind, quality, color, or ornamentation desired. Paper ofmedium thickness will answer the purpose, or the papers made with a viewto stiffness, strength, and other qualities may be employed, or if desired the paper may be prepared in different ways-such as giving it oneor more coats of silicate of soda or vitreous paint, or covering it withthin metal foil or with powdered bronze, using silicate of soda orsimilar substance for a size. Such preparations serve to stiffen thepaper, and,by rendering its surface highly glossy or brilliant, impartto it charae teristics of a reflector, and to a considerable extentincrease the light directed downward by the shade. Thinly-shaved wood,cloth, leather, and similar substances properly stiffened, may be.substituted for the paper.

The several pieces described are united together in the followingmanner: The inner circular edged (l,of the piece B is lapped over theouter circular edge,e e, of the piece A, as shown in Fig. 3, and the twoare firmly pasted or cemented together. A lap of about from a quarter tohalf an inch is sufficient, and in making the lap one end of the pieceBis allowed to extend beyond the end of the piece A, so as to form ashoulder, as shown at f, which will permit the two ends 9 and h to bebrought together and lapped without lapping over the piece A. Any pasteor cement which will not be affected by the heat may be used, silicateof soda answering the purpose. After the pieces are cemented together,as described, the two ends or edges 9 and 71., Fig. 3, are brought roundand together, one of which, 9, is lapped over and cemented to the other,11, so that the edges of the piece A are simply brought together and notlapped. This leaves or forms aslit which extends upward through thepiece A and gives it spring or play, so that it readily adjusts oradapts itself to the chimney under different conditions of temperature.

The shade so made,when required for use, is simply slipped over thelamp-chimney, as shown in Fig. 4, resting upon and in direct contactwith the chimney,the paper being completel y protected against the heatby the asbestus, and in such a manner that it cannot by accident orcarelessness be burned. Ashade of the ordinary size has a diameter ofabout per against being injured by the heat, subten inches at the lowerend, and a hole about stantially as set forth. two inches in diameter-atthe top; but it is In testimony whereof I have hereunto set obvious thatthe shade may be made of differmy hand and seal, in the presence of twowit- I 5 5 entforms and sizesand adapted to [it anylamp. ness, in thecity, county, and State of New What I claim as new, and desire to secureYork, the 24th day of March, 1886. by Letters Patent, is
